Can’t find the icon?

The icon only appears when an email is open. Make sure you’ve clicked on an email to open it — it won’t appear in the inbox list view.If you’re in Outlook desktop and still can’t see it, check under More commands (…) in the ribbon, or go to Home → Apps → My Add-ins to confirm CoreGPT is enabled.
Try these steps:
  1. Refresh the page (OWA) or restart Outlook (desktop)
  2. Sign out of CoreGPT and sign back in
  3. Disable and re-enable the add-in from Manage Add-ins in Outlook settings
In classic Outlook, the button appears in the ribbon under the Home tab when reading an email. If you can’t see it, click the … (More commands) button at the end of the ribbon — it may be hidden due to screen width.
This usually means the add-in needs a moment to load. Wait 5–10 seconds and refresh. If it stays blank, sign out and back in from the CoreGPT panel.
